"Ay, they seem firm enough, but it may be that one of them is wedged in, and that when the wedges are taken out it could be pulled off."
"I think you would have noticed it, John. If there was anything of that sort it must be outside. However, we will take a good look round the yard to-morrow. The warehouse is strongly built, and I don't believe that any plank could be taken off and put back again, time after time, without making a noise that would be heard in the house. What do you think, Cyril?"
"I agree with you, Captain Dave. How the thieves make an entry I can't imagine, but I don't believe that it is through the wall of the warehouse. I am convinced that the robberies must have been very frequent. Had a large amount been taken at a time, John Wilkes would have been sure to notice it. Then, again, the thieves would not come so often, and each time for a comparatively small amount of booty, unless it could be managed without any serious risk or trouble. However, now that we do know that they come, we shall have, I should think, very little difficulty in finding out how it is done."
"You may warrant we will keep a sharp look-out," John Wilkes said savagely. "If the Captain will give me the use of a room at the back of the house, you may be sure I shan't close an eye till I have got to the bottom of the matter. I am responsible for the cargo below, and if I had kept as sharp an eye on the stores as I ought to have done, this would not have happened. Only let me catch them trying to board, and I will give them such a reception that I warrant me they will sheer off with a bullet or two in them. I have got that pair of boarding pistols, and a cutlass, hung up over my bed."
"You must not do that, John," the Captain said. "It isn't a matter of beating off the pirates by pouring a broadside into them. Maybe you might cripple them, more likely they would make off, and we want to capture them. Therefore, I say, let us watch, and find out how they do it. When we once know that, we can lay our plans for capturing them the next time they come. I will take watch and watch with you."
"Well, if it goes on long, Captain, I won't say no to that; but for to-night anyhow I will sit up alone."
"Very well, let it be so, John. But mind, whatever you see, you keep as still as a mouse. Just steal to my room in your stockinged feet directly you see anything moving. Open the door and say, 'Strange sail in sight!' and I will be over at your window in no time. And now, Cyril, you and I may as well turn in."
The night passed quietly.
"You saw nothing, I suppose, John?" the Captain said next morning, after the apprentices had gone down from breakfast.
"Not a thing, Captain."
